(Ghana sanitation truck hydraulic cylinder,produced by Hengyu Group）

sanitation truck hydraulic cylinder are widely used in Ghana，because of high work efficiency，long service life，smooth movement.So our company has designed sanitation truck hydraulic cylinder for customers from Ghana.

Introduction to sanitation truck hydraulic cylinder:

The definition of the minimum stable speed refers to the minimum movement speed of the sanitation truck hydraulic cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the sanitation truck hydraulic cylinder that undertakes different work has different requirements for the minimum stable speed.

When the hydraulic oil is not pumped into the sanitation truck hydraulic cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the sanitation truck hydraulic cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

When the sanitation truck hydraulic cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the sanitation truck hydraulic cylinder is badly worn, it can be repaired by grinding the mandrel or honing on the boring machine. If the piston is worn, it can be repaired by electroplating, and serious wear should be replaced.

sanitation truck hydraulic cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the sanitation truck hydraulic cylinder is placed for a period of time, the sanitation truck hydraulic cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.

Answers to some questions about sanitation truck hydraulic cylinder:

Servo cylinder control principle
The electro-hydraulic pulse servo cylinder is composed of a stepper motor, a three-position four-way servo valve, a mechanical feedback device (a wire carrier) and an oil lever. When the stepper motor gets a pulse signal, its output shaft rotates 1.5 or 3 degrees, the servo valve spool drives the wire to rotate at the same time, the valve spool moves and opens the reversing cylinder to output pressure oil, the piston moves and drives the lead screw to reverse rotate the valve spool back to the original position, and the servo valve stops output pressure oil in the center. At this time, the cylinder moves 0.1 or 0.2mm stroke, and the displacement and speed of the cylinder travel are determined according to the given value of the electrical pulse.

How to use a solenoid valve to control the expansion of a cylinder? Doesn't the solenoid valve only control on/off?
Use the solenoid valve P into A-B (generally equipped with oil circuit board) to connect the oil inlet interface at both ends of the cylinder, and the solenoid valve can be realized by power off (refer to the solenoid valve 2B2L, different solenoid valve actions are different).
